  • Currently Unavailable until January, 2022.
  • Shipping leadtime: 1-2 business days.


EternaBond AlumiBond AS-2-50 can be used on virtually all roofs, walls, floors, gravity tanks, troughs, etc. UV stable and moisture tight, this tape creates an air and vapor barrier. The thick 4 mil aluminum backing combined with EternaBond’s advanced MicroSealant creates a hard surface.


  • Available in 2, 4, and 6 inch widths.
  • EternaBond AlumiBond leak repair tape has a heavy aluminum facing (requires no UV protection).
  • The aluminum facing is 4-mil thick aluminum sheet (not 2-mil foil like roof-seal most tapes). Tape is 20 mils thick.
  • The specialized backing has proven to be UV stable, even after 16 years in full sunlight.
  • The patented adhesive has an integrated primer which allows AlumiBond to BOND with the surface it is installed on.
  • Perfect for re-seaming all roofs, regardless of the material, AlumiBond makes a permanent water-tight seal (except silicones). Also great for tank repairs.
  • Elongation factor greater than 700% guarantees AlumiBond will flex, expand and contract in all conditions, even on liners.
  • Can be installed to -20 degrees F (with EternaPrime).
  • Sag rating of over 250 degrees F.


EternaBond AlumiBond bonds to a wide range of materials including carbon steel, aluminum, galvanized steel, aluminum foil, gypsum board, wood, rubber, tar, polyethylene, polypropylene, polystyrene, fiberglass, brick, concrete, masonry, rubber, thermoplastics, single-ply roofing, etc (everthing except silicone contaminated surfaces). AlumiBond remains flexible to temperatures as low as -70 degrees F making it virtually impossible to thermally shock the roof causing a leak. AlumiBond is recommended for all types of metal roofs and ducting including:

  • Trailers / RV's
  • Mobile Homes
  • Metal Buildings
  • Duct Work (rooftop and severe environments).
  • Industrial Buildings
  • Roof Awnings
  • Truck Trailers
